Limbal ring
A limbal ring is a dark ring around the iris of the eye. It is a dark-colored manifestation of the corneal limbus resulting from optical properties of the region. Limbal rings become less pronounced with age, thus darker rings imply youthfulness and are considered attractive. Some contact lenses are colored to simulate limbal rings. == See also ==
